This invention relates to an antitheft device which is attached to goods displayed at a counter and a show window, and it gives an alarm when removed. Conventional alarm output means for outputting alarm information includes a speaker, etc., for generating an alarm sound, but when a plurality of such antitheft devices are arranged adjacent to one another, it is not possible to instantaneously discriminate which device generates the alarm sound. The antitheft device of the present invention includes a case (2) fitted to an object article (E) to be protected, detection means (P) for detecting preliminary actions of theft, alarm output means (Q) for outputting alarm information on the basis of detection information of the detection means (P), and light emission means (20) disposed inside the case (2) for emitting light outside the case (2) on the basis of detection information of the detection means (P). Therefore, even when a plurality of antitheft devices are disposed adjacent to one another, it is possible instantaneously discriminate which device outputs the alarm information, by watching which device emits light. <IMAGE>
